Probably not the most practical attack, but it is very possible to MITM the connection between the keyboard itself and the motherboard.

A similar project is rr[0], which is freely available. Like you said, I find that reversible debuggers are a huge improvement over regular debuggers because of the ability to recor…

Intel has an implementation of this technique here as well: https://github.com/intel/hyperscan

Yes, this is on a single 8GB 2667MHz DIMM in a laptop. edit: For dual channel RAM, I would suspect the throughput depends on how the kernel decides to map physical memory to virtua…

> I doubt my current garage band could afford the OP just this moment, but I sure wish we could! Well, I intend to finish high school at a minimum before pursuing employment :)

This was actually considered, and other libraries do ignore checksums, or at least have options to: https://github.com/richgel999/fpng/issues/9

Unfortunately I haven’t had the time to do a proper benchmark, and the fpng test executable only decodes/encodes a single image which produces very noisy/inconclusive results. Howe…

Not sure if any of these would result in meaningful performance gains, but a few ideas I had: * An avx96/avx128 version, which requires more care than avx32/avx64 because you will …

Wouldn’t it be more than one person per computer though, seeing as it’s a "home" computer that would likely be shared?

You can debug programs that ran in the past using debuggers like rr[0], which support both recording execution for later debugging, or stepping backward in a running process. [0]: …

#3 really resonates with me, writing about topics that I think I know well enough to share online often reveals gaps in my understanding and new insights. I used to think that appl…

I use blogging to achieve a few goals of mine: * Solidify my knowledge in a given topic (the best way to find out how well you really know something is to try to teach it) * Improv…
